Matthysse, the hard-hitting Argentine with a record one split decision shy of perfection, has been predicting a knockout all week. “Look, I traveled thousands of kilometers in training and flying here for this fight, and I didn’t come to take a picture with Don King," he said. "I came to beat Devon Alexander, and I will."

The extremely dangerous Devon Alexander hasn't taken too kindly to his opponents fight predictions. “Lucas say he gonna knock me out. The last guy that said that to me [Juan Urango] got knocked out. I don’t talk trash. I let my hands do my talking for me. Just like our T-shirts today say, ‘R-E-D-E-M-P-T-I-O-N’ is going to happen on Saturday night.”

Promoter Don King stood between the two men, taking it all in. "You see, this is the Show Me State," he said. What does that mean? It means these fighters can talk all they want today, but come Saturday night they are going to have to show everyone what they are made of.”
